Exporting textures from Unity

New to Unity here. Am building an attractor loop video based on a Unity project. There were objects that were built directly into the Unity project using a plugin. I’m trying to determine if there is any way to export those textures back out of Unity for me to use for matching purposes in the video

You might find Texture2D.EncodeToPNG and Texture2D.EncodeToJPG useful. Check the sample code in the first one.
